Mirrorless power zoom adapter

The New Camera Exclusive – As we have already seen the Canon power zoom PZ-E1 adapter (Amazon) enables electronic zoom control for some Canon lenses in DSLRs. In a recent patent (2017.7.20) published by Canon, they are working on advance power zoom adapter for Mirrorless camera lenses. In the patent image we can clearly see camera shown in the image for reference doesn’t carry any Mirror inside, We do hope the next gen of power zoom adapters for mirrorless will carry more advance core specs.
